Enum UploadPathScheme 

pub enum UploadPathScheme<'a> {
    ExerciseService {
        exercise_service_slug: &'a str,
    },
    Answer(&'a AnswerUploadDestination),
}

Where an upload’s objects are stored, and what the upload route hands back for them.

Variants

ExerciseService

<exercise service slug>/<random> and a permanent url naming that path, for files that belong to course content rather than to one student: a teacher’s spec files, and the playground’s throwaway uploads. The slug carries no authorization meaning.

Fields

exercise_service_slug: &'a str

Answer(&'a AnswerUploadDestination)

answers/v1/<course|exam>/<owner>/exercise/<exercise>/user/<user>/<file upload>, so a retention or takedown rule can find every object of one course, exercise or student without reading the database, and every object leads back to its row.

The path names the student, so the url handed back carries a claim instead of the path.

Implementations

impl UploadPathScheme<'_>

fn path(&self, file_upload_id: Uuid) -> String

Where one file of this upload is stored. Applies to new uploads only: old rows keep the layout they were written under, since nothing derives a path from a row.

fn download_url( &self, file_upload_id: Uuid, path: &str, file_store: &dyn FileStore, app_conf: &ApplicationConfiguration, ) -> Result<String, ControllerError>

The url the upload route hands back for one stored file.
